When you combine increase with monotonically you rule out the
possibility that it is equal.
However I'd expect for an index you want increasing by one, which is
more strict than monotonically increasing.
...
For most integer-indexed tables, the interval between index values is
irrelevant.
The values just need to be different. The GetNext and GetBulk operations used
to retrieve information from tables just rely on a notion of greater-than.
Gaps appearing in the sequence of values seen as indexes in retrieved data
may occur for many reasons, including the application of access control policy,
so a management application that relied on them having an interval of 1 would
be asking for trouble. A robust management application won't even assume that
table entries will come back in the correct order, since some SNMP agent
implementations get this wrong for some cases.
